摘要
结合消防员灯具实战使用场景,通过模拟真实火场环境中的烟雾、选配光密度计等检测仪器、研制遮光装置等关键部件,建立了安全可控的试验装置及方法环境。开展了不同便携式消防灯具在不同烟雾浓度和不同反光环境中照射性能试验,获得了较为全面的试验数据,建立了灯具照射性能与烟雾浓度、反光系数之间的数学模型,反映了灯具照射性能在不同烟雾浓度、不同反光系数环境中的变化规律。
By combining the actual usage scenarios of fire luminaries,a safe and controllable test apparatus and method environment had been established in this paper by simulating the smoke in the real fire environment,selecting the detecting instruments such as op- tical density meter and developing the key components such as shading devices.Meanwhile,the illumination performance test of different portable fire luminaries in different smoke concentrations and different reflective envsronments had been carried out in this paper,the comprehensive test data was obtained,and the mathematical model between the illumination performance of luminaries and the smoke concentration,reflective coefficient had been established,which reflected the variation law of the illumination performance of luminaries in the different smoke concentrations and different reflective coefficient environments.
